TIRE FOR VEHICLE-WHEELS.

Specification of Letters Patent.

Patented Nov. 9, 1909.

Original application led November 23, 1908, Serial No. 464,169. Dividedand this application led February 10, 1909. Serial No. 477,040.

To all whom it may concern:

Be it known that I, Trionasi Minennr, a citizen of the United States,residing at lVorthington, in the county of Franklin and State of Ollio,have invented certain new and useful Improvements in Tires for`Vehide-Wheels; and I do hereby declare the followingto be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame. l

My invention relates totires for vehicle wheels, has especial referenceto pneumatic tires designed for use on wagons or trucks for carryingheavy loads, has for its object the construction of tires capable ofsustaining great Kweight and yet being sulliciently resilient to yieldto irregularities in or obstructions on a road-bed, and the inventionconsists in certain improvements in construction, which will be fullydisclosed in the following specification and claims.

In the accompanying drawings, lwhich form part of thisspeciicationf-Figure 1 represents a side elevation partly in section ofa tire embodying my invent-ion. Fig. 2

, is a plan view, on an enlarged scale. Fig.

3 is a transverse section, partly in elevation. Fig.- 4 is a plan viewof one of the' treadcarriers detached. Fig. '5 is a plan viewof one ofthe tread-members detached. Fig. 6

`is an end view of the same. F ig.l 7 is a detailk of one of theresilient members forming the l members 9 .of the sides of the casingare sides of the casing.

lic

.the outer side 12 of the base Fig.` 8 is a like view of one of the metamembers forming the sides of the casing. Fig. 9.is an edge View of thesame. Fig. 10 is a detail plan View showing the links and theirconnections.

Reference being had to the drawings and the' designating charactersthereon, the numeral 1 indicates the metallic rim, 2 the felly of avehicle wheel, 3 the inflatable or pneumatic inner tube, 4 the tirecasing, 5 the metallic tire bands forming the base or seat of thecomposite sides of the casing, and 6 the metallic clamping-rings forsecuring the tire as a whole to the vehicle wheel by means of bolts 7,or in any preferred manner. The bands 5 are made of metal and areprovided with a rib 8 to which the metallic secured by rivets or bolts10 or the' like, and the flange 11 of the' clamping ring'6 engages ofthe band5, as shown in Fig. 3,

The sides of the-casing 4, are composed 17 at their upper ends toreceive metallic links 18, and `with a slot 19 at their lower ends toreceive the ribs 8 on the bands 5.

20 indicates detachable sectional metallic tread-carriers or supportspreferably made of .sheet steel stamped into form, on which sectionalotread-members 21 of rubber or other resilient material are supported andare separately removable and renewable as A the tire Wears, withoutproviding an entire new tread for the wheel.

Each member 21 is provided with a transverse opening 22 to receive oneof the bolts 16, and with slots 23 and 24, the former to receive links25, which are also engaged by the bolts 1.6, and the latter slot 24', toreceivt` the link 26 placed between each pair of links 25, 25, whichlink 26 is engaged by adj acent bolts 16. Each link 18 is engaged at oneend by the bolts 16 and is connected to the adjacent link at itsopposite end by a rivet 27, as shown in Figs. l1 and 10. The links areunder the tread-members 21, extendthroughout the circumference of. thecasing, one set of the links 18 on each side, and one set ofv the links25,25 and 26 in the transverse center of the casing.

The tread-carriers 20 are provided with laterally extending flanges 29which project out sulciently to cover the heads and the nuts of thebolts 16, as shown in Fig. 3 and are en a ed by the bolts 16 whichextend throng 1 t e walls 30, thereof.

The links 25, 25 and 26, and the links 18, and the transverse bolts 16,take the strain on the periphery of the tire and contribute materiallyto the strength thereof, wlnle the sectional tread-members 21 take thesurface wear ofthe tire, and are separately renewable as required.

The composite sides of the tire-casing are suliiciently resilient toaccommodate the flex-- ure of the sides and yet are of such strength asto sustain the weight generally carried vby trucks or other vehicles fortransporting heavy loads.

carriers 20 to protect the inner tube from' wear and allow said tube toassume a rounded form on each side under the filling pieces 32.

It is obvious that changes may be made in the details of construction ofthe several parts without departing from the spirit of my invention.

The primary features of my invention are claimed in my application,Serial No. 64,165), of which this application is a division.

Having thus fully described my invention, what I claim is` l. A tire forvehicles provided with a cas-A ing having composite sides of separatememers, part of which are resilient, tread-carriers, tread-sections onsaid carriers, links extending throughout the circumference of thecasing, and transverse bolts engaging said sides, tread-carriers andlinks.

2. A tire' for vehicles provided with a casing having separate sidescomposed of alternate flexible and inflexible members, tread# carriersinterposed between and covering the periphery of said sides, a separatetread, reinforcing links below the surface of the tread, and transversebolts engaging the inflexible members of the sides, the tread-carriers,the links and the tread.

3. A tire for vehicles provided with a casing having separate sides, aseparate tread, reinforcing metallic links on each side of the casingand between the sides, and transverse bolts engaging said sides, linksand tread.

4. A tire for vehicles provided with a casing composed of separatedetachable sides, a separate detachable tread, transverse bolts engagingsaid sides and tread, an inflatable inner tube, and an interposed liningbetween said tube and tread.

5. A tire for vehicles provided with a casing composed of separate sidesof alternate flexible and inflexible members, base-plates for engagingthe rim 0f a wheel, and to which said sides v are secured, a separatetread, reinforcing metallic links engaging said sides and said treadbelow the surface of lthe tread, and transverse bolts engaging saidsides, links and tread.

In testimony whereof I alix my signature, in presence of two witnesses.
